The former Villa midfielder has stepped down from his position as a first-team coach at the Premier League outfit.
One Villa fan has a theory why Petrov made his decision and posted his thoughts on Twitter, to which the former Celtic midfielder has responded.
Villa have been truly poor so far this season and are in real danger of getting relegated from the Premier League.
The Villans, who are without a permanent manager at the moment, are at the foot of the league table with just four points from 10 matches.
Villa will take on Tottenham Hotspur away from home at White Hart Lane in the Premier League later today.
Spurs are currently sixth in the standings with 17 points from 10 matches, just four points behind fourth-place Manchester United with a game in hand.
